Description

Turn any standard analog load cell into a wireless load cell!  The TBX Wireless Load Cell Bridge System replaces the physical cable connection between the load cell and the weight indicator. This can be retrofitted into old systems or designed for new systems.  The TBX-T can be used in conjunction with the TBX-R as a wireless, Bluetooth link between cell and indicator.  Alternatively, the TBX-T can be used directly with software to display/log the load cell’s reading. See the graphics of the TBX Wireless Load Cell Bridge System below for details.

 

Working modes
1. Load cell – TBX-T (Transmitter) – TBX-R (Receiver) – weight indicator

Working modes

2. Load cell – TBX-T (Transmitter) – mobile app (replacing the weight indicator)

Advantages of TBXs

  • Ultra-low energy consumption
  • Receiver powered directly from the load cell connector (no external power supply)
  • Indication of low battery status (via RS 232 port and LED diode)
  • Clamp connectors (vibration resistant)
  • Energy saving mode (sleep mode in the absence of a change in mass value)
  • An additional LED module indicating the status of the system
  • Many systems can be operated in one location (128 channels can be selected)

Types of load cell configurations

Types of connections
1. Load cell – TBX-T (Transmitter) – TBX-R (Receiver) – weight indicator

 

 

Types of connections
2. Several Load cells – TBX-T (Transmitter) – TBX-R (Receiver) – weight indicator

 

Types of connections
3. Several TBX-T (Transmitter) connected to one – TBX-R (Receiver). To one TBX-R (Receiver) you can connected up to 4 (pcs) TBX-T (transmitters)
